How to build out accurate shipping cost for products shipped via several third party sources.
Treepl CMS Ecommerce system calculates (UPS, FEDX) shipping cost to delivery zip code from only one originating third party supplier zip code. This assumes all products are fulfilled from one third party supplier. In this case there are several fulfillment sources. Different products are drop shipped from different fulfillment sources.. Please advise if/how this could be developed?
